摘　　要：近年来,许多研究主题都集中在无线网络中作为可扩展路由协议的集群算法的研究传感器网络。在这些算法中,通过使用数据聚合技术和减少应采用的传感器进行长距离通讯,总能耗网络寿命缩短。针对传感器能量有限的问题,论文提出的一种新的算法DECSA,该算法是基于经典聚类的改进算法LEACH。通过考虑节点距离彼此和节点的剩余能量,DECSA算法尝试选择适当的节点作为CH。另外,在此算法中旨在产生一个多层次的聚类层次结构,并基于CH到基站的距离,选择了一些CH作为基准站CHs。论文基于DECSA算法和负载均衡提出了聚类算法。该算法结合了DECSA支持最低和最大可接受负载这两个门槛。因此,当群集在一帧中加载时小于最小阈值,则群集的帧为展开,并且大于最大阈值时,每个帧中群集负载的一部分被转移到第二个CH节点。In recent years,many research topics have focused on the research of cluster algorithms as a scalable routing proto-col in wireless networks.In these algorithms,by using data aggregation technology and reducing the number of sensors that should be used for long-distance communication,the total energy consumption network life is shortened.Aiming at the problem of limited sensor energy,this paper proposes a new algorithm DECSA,which is an improved algorithm LEACH based on classic clustering.By considering the distance between the nodes and the remaining energy of the nodes,the DECSA algorithm tries to select the appropri-ate node as the CH.In addition,this algorithm aims to generate a multi-level clustering hierarchy,and based on the distance from the CH to the base station,some CHs are selected as the reference station CHs.This paper proposes a clustering algorithm based on DECSA and load balancing.The algorithm combines the minimum and maximum acceptable load thresholds supported by DECSA.Therefore,when the cluster is less than the minimum threshold when it is loaded in a frame,the frame of the cluster is expanded,and when it is greater than the maximum threshold,a part of the cluster load in each frame is transferred to the second CH node.
